I would be grateful if anyone could advise me as to a late planting variety of potatoe available in S.A. It appears that the variety favoured in the USA is Butte. Any advice would be most welcome

As from 2010 I have been planting potato seedlings in my backyard garden what I noticed is that they do not flower for pollination to take place but when I harvested them I got big quality tubers. The following year I planted the potato seeding in winter and they thrived well but the same thing of not flowering happened again and the harvest was good. This is surprising me really ,. What could be the reason for these potato plant not flowering but able to form tubers.

Hi Can potatoes be planted in a tunnel or does it need bees for polination?

You certainly can grow potatoes without chemical sprays and fertilisers. Potaoes have been grown for hundreds of years without them. The soil needs to be friable or cultivated to at least 200mm (8") deep and have old manure worked into it. Plant the potato pieces about the same depth in the soil then cover. This depth is to reduce the chance of potato moths getting to the tubers to lay eggs. As the potato shoots emerge hill up around the stems with more soil or mulch and keep them watered. Potatoes are generally pest free and rewarding and a few can be scratched out about a month after flowering with the remainder harvested when the tops die off. Store the potatoes inside or in an airy, insect-proof container away from light. All the best with your potato growing!
